Ten-year storm intensities are estimated by the National Oceanic and Atmospheric Administration(NOAA) Precipitation Frequency Data Server(PFDS), which is herein incorporated by reference, including subsequent amendments and editions, and may be accessed at no cost at http://hdsc.nws.noaa.gov/hdsc/pfds/. Please revise calculations as it appears the 10- year 24 hour storm was used. 4.

Bioretention cells without pretreatment are more prone to failure than bioretention cells with pretreatment. Not providing pretreatment will require more frequent maintenance of the bioretention cell which will result in a higher cost of ownership over the lifetime of the SCM. Please consider revising the design to include pretreatment. To ensure a fair, timely, and transparent review process, any disagreement with provided comments will need to be addressed in writing as part of the requested information resubmission, within the required resubmittal window. The merits of the disagreement will be reviewed during the next scheduled technical review and, if applicable, will be addressed in further requests for additional information. If the resolution provided by the reviewer is found to be unsatisfactory, the applicant can agree in writing to a longer review period, during which the dispute will be brought to the technical review committee and a final determination will be made. Due to staffing limitations and to ensure an efficient project review, requests for individual meetings to discuss provided comments are decided at the discretion of the reviewer. We encourage you to carefully review the written feedback provided and the applicable rules. The NCDEQ Stormwater Design Manual provides additional insight into design criteria. Any questions or further requests for clarification should be submitted in writing in the requested information resubmission,within the required resubmittal window. We appreciate your understanding and cooperation in this streamlined process. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to August 18, 2024, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. Please reference the State assigned project number SW5240102 on all correspondence. If you need additional time to submit the information,please submit your request for a time extension to the Division at the contact below. The request must indicate the date by which you expect to submit the required information. The Division is allowed 30 days from the receipt of a completed application to issue the permit. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.
